Product Description

Bought a rail but need a good gas block? Like fiddling around with your gas hole? Look no further! Weighing in at 1.3oz, this .625 gas block is fully adjustable via a screw in the front and lockable via a screw in the side. This block is attached to your barrel by compression which is attained by tightening the three screws on the bottom. It is suggested that a REMOVABLE thread locker of your choice be used on the screws.

Each gas block comes with a roll pin so there is no need to hunt one down at your local store!

I wasn't sure about buying from a place unknown to me, but when I saw they were a small company behind enemy lines (California) I decided to go for it.
I was not disappointed. This gas block is top notch. Machining and finish looks flawless. Very easy to attach and adjust. It holds rock solid onto the barrel so if you are worried about it being a clamp, don't be. I put it on to test it out before finishing my upper build and I could not move it. It has 3 screws holding it in place, after taking out 2 of the screws i thought Id see if I could adjust it. Couldn't even move it when it had only 1 screw in it.
This would be an excellent gas block for the price even if it cost twice as much.

good functioning adjustable gas block

I despise set screw gas blocks. Clamps are infinitely more secure. I’ve used yankee hill clamp blocks but they are bulky and don’t work with a lot of slim rails. These would fit any slim rail I’ve ever seen and have very tight tolerances, smooth finish. Not sure about the adjustable part I’ll probably loctite it down full open as I’m running it on a rifle length faxon gunner barrel but for a carbine length it might be beeficial as they are way over gassed.

would recommend to anyone

Finish looks better in person than online. All the threads are super smooth. Very light and gets the job done. Wojtek is a great place to buy from. I am looking forward to other products.

Perfect fit, finish is excellent and tuned in no time.

I was surprised at the quality for that price. I use a lot of pencil barrels that need adjustable gas with 625 diameter but there so expensive ....these gas blocks are very nice and light weight. I will be ordering more of them and shipping is very fast. ...that's a plus

Good gas block

Well-machined, small (fits easily under ALG EMR V1), light, and clamps down securely on a Faxon pencil barrel. Most importantly, the block works. Order was quickly processed and shipped. Would buy again.
